- means for cooling the smoke and for absorbing its undesirable elements which may be I wound upon tube re laced when saturated. This object is at-.

tamed bythe means illustrated in the accompanying drawings, in wh1ch- Figure 1 is a longitudinal a pipe embodying my invention. Fig. 2 is a cross-section upon line 12 v, Fig. 3 is a simi ar view upon I s a perspective view 1, upon an enlarged scale. line a: at, Fig. 1. f Fig. 4i

of the tube of the stem. Fig. 5 1s a similar view of a modified form of tube. Fig. 6 is a cross-section upon line w w, Fig. 5.

Referring to the parts, bowl A hasv a short annular extension a, which has an enlarged central bore a, at the inner end of which is an annular recessa for collecting moisture.

The stem consists of an intermediate tube or plug B, a central plug C, and an external wrapping D. I

In the form shown in Fig. 1 tube B has a series of longitudinal grooves I) cut in its peripher'y. Grooves b are cut through the tube at one end and only partially through it at the other end. A

Plu Cand wrapping D are made, preferably, om paper. After the wrapping Dis B it is placedin bore a at one end. A mouthpiece E is placed over it at the other end.

The smoke passes through grooves b and comes in contact both with the external sectional view of wrapping and with the plu which absorb the eleterious substances f iom the smoke. Wrapping D beingthe only thing between the smoke and the air, the smoke is much cooled in passing through the stem. After the absorbing materials have become laden with the un esirable constituents the ma be readily removed from tube B, and free ngatgrial may be placed quickly in their s ea addition to external'grooves b a series of internal longitudinal grooves 12. This tube is to be wra ped and is to contain a plugsimilarly to t e form illustrated in Figs. '1 to 4. The smoke passes both through the external and the internal grooves of the tube, coming in contact'with the absorbent and yielding up its undesirableconstituents.

WhatI claim is v 1. A tobacco-pipe having a stem consisting of a tube grooved longitudinally, an external wrapping and internal plug of absorbent materia 2. In a tobacco-pipe the combination of a bowl having an'annular extension with an enlar ed bore, a stem consisting of a tube externa 1y grooved and a wrapping of absorbent material, and a mouthpiece for engaging the end of thestem. i

. 3. In a tobacco-pi bowl having an annu ar extension'with an internal bore, a stem engagin the bore and consisting ofa tube longitu inally grooved externally and internally, upon the exterior a wra ping and u on the interior a plug of absor ent materia and-a mouthpiece engaging the end of the stem.
